There is a strange tower that exists in many worlds, many places, many times. The Tower Between Worlds is a six-level spire in every version, but the interior (and often parts of the exterior also) can be quite different from each other. One element that each version of the tower has is the fifth level of the tower where the “tower shifting” mechanism is. On the fifth level (the upper left level on the map), there are four magical “tables” built into the wall, each with a small orb on it. Each corresponds to one of the versions of the tower, and any attempt at picking up an orb immediately transports everyone on that level of the tower to the corresponding tower (and the orb remains where it was – they cannot actually be removed from their respective tables). But it turns out there are more than four towers, and each tower might have different orbs on its four tables.

The tower layout goes from right to left, bottom to top – so the ground level on the lower left, level 2 on the lower right, level 3 on the middle left, etc.

The City Tower is crowded into a tight city block of lower structures and sees few visitors. It is also a bit of an eyesore, as the fourth level has had much of one wall destroyed, and a semicircular wooden platform erected there supposedly to effect repairs but acting more as an observation deck over the rooftops of the city. Many levels are decorated with full book shelves, making the tower into something of a library in feel. The central spiral stairs lead up through every level of the tower, from the well-secured ground floor to the bedroom with woodstove up on the top level.

This tower sits amid the brilliant blue crystalline outcroppings in the infinite wastes of the Cobalt Hells. The base of the tower is a massive growth of brilliant blue crystal with the masonry of the three upper levels being made of a darker blue-grey stone. The whole place is hot and unpleasant, like the hells around it. The first two levels are connected by a roughly circular set of stairs that lead up along the centre of the tower. The third floor is sloped upwards from the top of the stairs leading to it until a full rotation around the centre of the tower gets you to the masonry-finished fourth floor where stone spiral stairs continue up to the fifth and sixth floors.

The first floor is a mess of broken crystals and debris, a stark contrast to the second floor and above which are clean and well-maintained and furnished with odd crystalline and metal furnishings, many of which don’t have an obvious purpose or form. The sixth floor has eight clusters of magical crystals of different colours – salt crystals collected from eight of the different hells. With these crystals as a focus, one can open gates or summon creatures from those alternate hells.

The Forest Tower exists in a small clearing in an immense forest that extends to the horizon in all directions. Based on the chains and collars here, the ground floor appears to have been used to hold prisoners or wild beasts. A workshop takes up most of the second level, and some strange arcane energies are in flux around a series of seven crystalline orbs on level 3. Access to level 5 (and the small garden boxes on the balconies) is via a ladder and trapdoor, and then up the central stairs to level 6 where eight small tables each display a preserved piece of fruit gathered from the forest surrounding the tower.

The Frozen Tower exists on an elevated deep southern mountain range on the edge of a huge glacier. Much of the base of the tower is locked in ice, and the upper level windows have broken allowing banks of snow to build up within the structure.

The lower levels are connected by stairwells. Access to the top two levels of the tower is via a ladder that comes up the centre of the tower. The purposes of the chambers on the various levels are difficult to determine – the tower has been abandoned for ages, and used as a shelter by locals on occasion.

The island tower is in the worst repair of its kin, standing alone on a tiny island barely big enough to support it. Most of the wooden stairs within have long ago collapsed and climbing up and down is a difficult process involving rickety ladders and a shakey set of stairs between levels 3 and 4 that is succumbing to dry rot. Getting up to level 5 requires exiting the tower on a wooden platform and climbing a ladder outside to the crumbling balcony above.

The Wasteland Tower stands in a desolate land under blood-red suns… It is home to the only tree for miles around – a gnarled and twisted ancient tree that pierces an upper window of the tower, seeming to reach for the dying suns overhead. Each floor is centred on this tree, and access to the sixth level (and someone’s secret bedroom up there) is only via climbing the tree itself.
